Application filed Ma ch 14, 1908. Serial No. 421,250.

heating apparatus constructed in accord-; ance with my invention; Fig. 2 is a. sectional view taken on the line 2-2 of Fig. 1 F ig. 3

is a sectional view taken on the line 3-3 of Fig. 1; and Fig. 4 is a detail perspective view of the main gasolene burner.

This invention relates to wax thread sewing machines. i

The main object of my invention is to provide a wax thread sewing machine having a. gasolene heating apparatus of novel con- 'struction which keeps several parts of the machine in a heated condition. I have herein shown my improved heating'apparatus applied to a wax thread sew1ng ma.- chine in which the shuttle is arranged above the work-table but it will, of course, be understood that said apparatus could be used on various other ty es of sewing machines without departing 0111 the spirit of my invention.

Referring to Fig. 1 of the drawings which illustrates the preferred form of my invention, 1 designates the wax-pot 0f the machine, 2 the shuttle mounted in the head 3 of the machine and 4 a vertically disposed flue which extends u wardly from the wax-pot to the work-tabii: 5. The takc-up .arn1 6 and the rolls 7 and 7*.0ver which the thread 8 passes are arranged inside of said flue, as shown in Fig. 1.

1A gasolene burner A is arranged underneath the wax- 0t 1 and the fuel is sup lied to said burner a pipe 9 which leads T0111 a. tank 10, a valve 11 bein provided for controlling the supply of asolene to said burner so as to regulate the ame from said burner.

A pipe '12 which is tapped into 8. lug 13 on head head will be kept heated. The flame from the pipe 14 plays directly on the plate 16 \land the heat which radiates from said plate the burner A leads to the head 3 of the machine, as shown in Figs. 1 and 3, and a pipe 14 which is tapped into a lug 15 on said burner leads to a plate 16.that is arrangedadjacent to the ta ie-up arm 6, said plate 6 projecting into the flue 4-,jas shown in Figs.

1 and 2. Gasolcne vapor from the burner A flows through these pipes 12 and 14 and the ends of sair pi es are spaced away from the head 3 and ate 16, respectively, so that the vapor w ich emerges from said pipes can be ignited and thus produce two flames that play on the head 3 and plate 16. The lame from the burner A hea'is the wax-pot 1 and the flame from the pipe 12 heats the 3 so that the shuttle mounted in said passes into the flue 4 and thus keeps the tahemp mechanism in a heated condition and also that portion of the" thread which, extends from the wax-pot to the work-table.

A flan e 17 which extends downwardly below thehottom of the wax-pot confines the heat from'thellame of the burner A, and the portion 17* ofsaid flange that is located at the front end of the wax-potis rovided with an opening 18 that permits the cat from the burner A to pass upwardly into the flue 4, as shown in Fig. 1, said portion 17 also being provided with a hole or opening 19 which enables dirt or wax to be removed from the bottom of the flue 4. While I have herein shown only one opening 18 it will, of course, be understoodthat the artl? could be provided with any desire number of openmgs.

When the valve 11 is manipulated to regulate the Ilame from the burner A the flames from the pipes 12 and 14 will also be regulatcd, thus producing a heating apparatus in which a single means; namely, the valve 11, is employed for regulating a plurality of flames. While I prefer to provide the machine with a pipe 1 that projects a flame onto the plate 6 for heating the thread and take-up mechanism, I do not wish it to be understood that my broad idea is limited to such a construction as heat from the bumer A enters the fiue,4- through the opening 18 and thus heats the members arranged inside of said flue. It will; of course, be obvious that I could ta other pi es into the. bur A in. cascit is esired to -a-at other parts i. the machine.
